Sorry, perhaps I misunderstood something earlier, these were measurements I took from my bike rather than from a spec sheet
I've heard good things about myvelofit getting you close. For background about where you are starting, you can look up your current bike measurements on geometry geeks, bikeinsights, 99 spokes, bike-stats, and quite a few more comparison sites. If your bike is listed, and you are running the default bar and stem, it is likely that they have all the measurements that you need to know your bike details. LCR018-D is on most of these sites. If you can't find your bike, get the dimensions from the manufacturer and load them manually on these sites for a custom comparison. This will be a good starting point. Then you might try to find reference bikes that you can touch, either by a friend or bike shop, possibly even renting something.
In my experience, the LCR018-D geometry is very close to my Santa Cruz Stigmata (in sizes 54), with the exception to of the long (+20 mm) toptube/ short stem combination that comes standard on the SC. Other close bikes to LCR018-D are Cannondale Synapse, ENVE Fray, plus many more endurance bikes that you can search. Cervelo Caledonia is not too far off. If you can ride any of these or find something comparable that you can access, that could be another way to zero in on an approximate fit. I found that to fine-tune my preferences, some extended experimentation with stem length and seat position on my SC was very helpful. I ended up trying +10, 20 and 30 mm on the stem, settling on +20. Adjusting bike and bar reach, this put me closest to a 120 length LC bar. Then there's also the crank length, but I suppose this could be fixed first since it will affect everything else. Lots of mid-size folks are moving to 165 mm cranks for a more forward position. Personally, I like the 165's. Shorter cranks usually require a taller saddle and allow for a slightly more forward seat position compared to longer cranks. If you haven't been riding much lately, you might check around to see if you ought to get some seat time to be more comfortable in a riding position before trying to fine tune everything.
